I'm too busy with work right now to give a thoughtful, measured response (and when you think of thoughtful and measured, think of me) but I'll get back to you. The evolution of language and the sociological ramifications of it is an interesting subject. Your point about commonly accepted idiomatic phrases was a good one and got me thinking, because I usually grind my teeth at the butchering of what I perceive as "proper English" here in the age of twitter. Going past minor annoyances, that put me on a train of thought about the power of words and their ability to mobilize people into tribalistic factions, a pretty war roomy subject for sure.
Anyway, back to my e-mails and messages and texts and shit, gotta make some money, be back later.
